She was last in 10 Downing Street during November last year when she attended the unveiling of her portrait - the first painting of a living politician to be hung in the official residence of the Prime Minister.

nepal 
Some 20 years after she left No. 10 Downing Street, a frail-looking Margaret Thatcher was back to visit with her Conservative successor, David Cameron.

Thatcher, 84, clung to the railing outside the famous black door as she walked up to the doorstep to pose for pictures. She waved to photographers, but made no comment.

Thatcher's visit Tuesday, which lasted about 45 minutes, came as the Conservative government said it was preparing what are likely to be the deepest cuts to public spending since Thatcher was in office. Britain's budget deficit is forecast to reach 10.4 percent of gross domestic product this year, and the government is under considerable pressure to slash expenditure.
